1 roots: This is the correct choice. A tree's roots are the part of the tree that goes underneath the ground, which absorbs water. This term is often used figuratively, however, to describe the "origins" of a person or object. In this broadcast, the rugby fan compliments the sport of rugby, saying it has "gentlemanly roots". She probably means that rugby is a distinguished, respectable sport.
2 referee: A "referee" is a judge who officiates a sports game. He enforces the rules of the game, deciding whether or not a player can keep playing after an offense. Note that in British English, "referee" also describes a person who can give further information about a candidate for a position (in US, this person is called a "reference").

"the root of a problem" = the origin of the problem.
origin: This is the correct answer. The "root of a problem" is the "origin" or "cause" of that problem. In another context, "roots" are the part of a plant which is underground and provides support, as well as water and minerals from the soil. Example: "In order to find a solution, we must first get to the root of the problem".
solution: "Root" does not share a similar meaning with "solution". The "solution" to a problem is the way to "solve" or "answer" it.
leader: The "leader (of an organisation)" is the person who organises it, or the person "in charge". A problem cannot have a leader!
result: The "result" of a problem is its "outcome" or "consequences". This is unrelated in meaning to "root".
